Abstract
Description
Technical Field
[0001] This utility model relates to the field of rescue stretcher technology, specifically to an adjustable shoulder strap type labor-saving stretcher. Background Technology
[0002] In the complex environment of mountain rescue, every rescue operation is a race against time and a battle against difficulties. When encountering injured or sick personnel, safely and quickly transferring them from rugged mountain terrain to a vehicle-accessible location is a crucial step in the rescue. Existing stretchers have the following drawbacks in terms of saving effort:
[0003] Traditional stretcher carrying is laborious: Traditional manual stretcher carrying requires the cooperation of multiple people, and long-term carrying can easily lead to fatigue of rescuers, affecting the efficiency and safety of carrying, and it is also difficult to keep the stretcher stable during the carrying process.
[0004] Ineffective auxiliary tools: Although some stretchers are equipped with shoulder straps, handles and other auxiliary carrying tools, they can reduce the burden on the hands to some extent, but their overall labor-saving effect is not significant and may affect the mobility of rescuers.
[0005] Portability and ease of transport are difficult to balance: While some folding stretchers offer improvements in storage, the folding structure often increases the stretcher's weight, leading to additional burden during transport. Furthermore, unfolding and securing them can be complex, requiring significant manpower and time.
[0006] Poor adaptability to complex terrain: Some wheeled stretchers are easy to move on flat roads, but in rugged, narrow or obstacle-filled terrain, the wheels may not work properly or even become a burden, and manual carrying is still required.
[0007] Imperfect multi-functional design: Stretchers with lifting, tilting and other functions often have complex mechanical transmission structures, which not only increases the cost and weight of the stretcher, but may also cause inconvenience in use due to mechanical failure, and the maintenance cost is also high. Utility Model Content
[0008] This invention aims to solve the technical problems of conventional stretchers being difficult to lift with arms and the stretcher carrier being prone to instability and tipping over.
[0009] To solve the above problems, this application provides the following technical solution:
[0010] An adjustable carrying strap type labor-saving stretcher includes a stretcher, wherein one end of the second vertical rod of the stretcher is fixedly connected to a first solid column, the outer wall of the first solid column is connected to the inner wall of one end of a first hollow column, the other end of the first hollow column is fixedly connected to one end of a hollow rod, the inner wall of the other end of the hollow rod is fixedly connected to the outer wall of the solid rod, the other end of the solid rod is fixedly connected to a second hollow column on the other side, the inner wall of the second hollow column is fixedly connected to the outer wall of the second solid column, the second solid column is fixedly connected to one end of the first vertical rod, and the hollow inner wall of the other end of the first vertical rod is fixedly inserted into a first insert rod, the inner side of the first insert rod is fixedly connected to a first crossbar and a second crossbar.
[0011] The first crossbar is fixedly connected to the first hollow section. The first hollow section is fixedly connected to the chest strap by multiple fixing ropes and several self-locking buckles. Multiple adjustable buckles are fixedly provided on the front side of the chest strap. Each adjustable buckle is fixedly connected to each shoulder strap. The shoulder straps are fixedly located on the back side of the chest strap.
[0012] The second crossbar is fixedly connected to the second hollow section.
[0013] The second vertical rod is fixedly inserted into the hollow inner wall of the other end of the second vertical rod, and the inner side of the second vertical rod is fixedly connected to the first hollow section and the second hollow section.
[0014] Handles are fixedly welded to the outer sides of both the first and second insertion rods.
[0015] The hollow pole is secured to the waist belt by multiple fixing ropes and several self-locking buckles on the outside. At least one self-locking buckle at one end of the fixing rope is used to lock the waist belt, and the self-locking buckle at the other end of the fixing rope is used to lock the hollow pole of the stretcher.
[0016] Both the first and second hollow columns are welded with handles, which are L-shaped.
[0017] The self-locking buckle at one end of the at least one fixing rope is used to lock the chest strap, and the self-locking buckle at the other end of the fixing rope is used to lock the first hollow section of the stretcher.
[0018] Handles are fixedly connected to the left and right sides of the other end of the stretcher.
[0019] Multiple sections of non-woven fabric are fixedly sleeved on the first and second vertical poles of the stretcher. Each section of non-woven fabric has two square ventilation holes. Sleeves are fixedly connected to both sides of each section of non-woven fabric, and the sleeves facilitate the sleeves to fit onto the side walls of the first and second vertical poles.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] 1. Adjustable shoulder strap stretcher: Equipped with adjustable shoulder straps, waist belt, and chest strap to reduce pressure on the shoulders and arms. The shoulder straps and waist belt ensure optimal comfort and support during transport, improving the efficiency and safety of carrying the injured person. Adjustable buckles are easy to operate for quick and easy securing and releasing of the shoulder straps and chest strap.
[0022] 2. Adjustable shoulder straps reduce the strain on the stretcher and the physical burden on the mover. The stretcher's shoulder straps, waist belt, and chest strap provide rescuers with a comfortable, safe, and efficient carrying tool.
[0023] 3. Shoulder straps and chest straps can evenly distribute the weight of the stretcher and the injured person to the shoulders, back, and waist of the porter. A waist belt can transfer the weight of the stretcher and the injured person from the waist to the legs, avoiding the traditional stretcher where the weight is borne solely by the hands and shoulders, thus reducing porter fatigue. When using the carrying straps, the stretcher's center of gravity is stabilized at the porter's waist during transport. Compared to the arms bearing the weight, this makes it easier for the porter to maintain balance and reduces the extra energy required to adjust posture due to instability.
[0024] 4. The stretcher is made of high-strength aluminum alloy, which reduces the overall weight of the stretcher while ensuring its strength and load-bearing capacity, making it easier to carry. The support structure on the stretcher reduces the difficulty of carrying and the physical exertion required.
[0025] 5. The shoulder straps and chest strap work together with the stretcher. The porter supports the weight of the stretcher through the shoulder straps and chest strap. During walking, climbing, and turning, the porter can control the direction with the help of the handles. The cushioning and adjustment functions of the shoulder straps and chest strap, as well as the stability of the stretcher, enable more labor-saving and efficient transport. When going downhill, the porters at both ends can use the waist belt, shoulder strap, and chest strap respectively to help control the downhill speed of the stretcher, reducing the braking force required by the porter's hands, improving transport efficiency, and reducing the burden on the porter. It is especially suitable for transporting wounded people in complex terrain or over long distances. Attached Figure Description
